Answer:
And we can find this probability using the normal standard table with this difference:
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And we can solve the problem using the z score formula given by:
Using this formula we got:
And we can find this probability using the normal standard table with this difference:
